The latest centrifuge for enriching uranium is 20 times more efficient as previous models

Hum... The previous model was gaseous diffusion.

The centrifuge technology —
which is expected to consume
about 95 percent less electricity
than the Paducah plant — operates
on the principle of centrifugal
force. Inside the 40-foot-tall
cylindrical machines are rotors
containing uranium hexafluoride
gas.

Usually centifuges are expected to use 40 times less energy than diffusion and Paducah is kind of old so, aside from increased volume, this sounds like a step backwards. Time to ditch those shares maybe?
